Antwoord op "How to fix this accessory may not be supported"None of these solutions work. My charger works fine, the issue is the adapter for my headphones. This is really annoying. I have an apple lightning phone jack and a used iPhone 7 that I just purchased. Unbelievable that I have to trudge to the Apple store. I really hope someone there has a fix or I’m going to be extremely upset. I can’t stream my news or a video or anything using headphones. This is one of the most important functions of the iPhone for me.
